32 hrs, no issues. Plugs changed at 25 hours and ski runs harder, Think Gap was original at 24, I left at 28 the way they came. How many hours prior to your plugs issues?

first time i changed plugs has at 64 hours.lol
but i think they last longer because in that time i ride every day.
since i start whit the denso plugs ive always have problems...
i think when i put now the pulley kit i will change to ngk cr9...

08 and both have ran fine except for a moment when a single spark plug fouled. I found this guy on youtube awhile back and he just bashes on the 250. He modified his engine and wonders why it blew, idk but he's kinda acting like a baby IMO Ive always expected the fact if if i put aftermarket parts on theres always a chance something will blow. He mentions that GIO problem is kinda to blame which i doubt is the problem, maybe if you let it go and do nothing about it for a decent amount of time.

well theres one thing for sure .. he was wide F43kin open when it let go... wonder if it was the rod or just plain old stupidity.
